Parameter

Default Value

Description

Parallel Script Count

Normal

The maximum number of scripts that can be executed simultaneously, possible values for this are Low : 5 simultaneous scripts, Normal : 10 simultaneous scripts and High : 20 simultaneous scripts.

Max. Timeout

1m

Fine tunes the low level network packets sending, indicating the maximal time to use for scanning a single host. This allows to abort a device scan when it takes too long.

Max. Inventory Timeout

6h

Indicates the global timeout for the whole session. The special value of 0 can be used to deactivate this option, that is, there is no timeout limit for the duration. Otherwise, the scan is aborted once the threshold value has been reached. The value in an integer followed by s for seconds or m for minutes or h for hours.

IP Address Range

80,1610,8080

Indicates the device range to be scanned. The expected format is a comma separated list of IP addresses or IP ranges. For instance, IP ranges must be supplied using different notations such as complete address range (192.168.0.0-192.168.5.254 ), a CIDR range (192.168.1.0/24 or 2001:db8:85a3::8a2e:370:152/896 ), a byte range notation (192.168.0-5.0-254 ) or single named devices (DNS, NetBIOS).nIt is strongly recommended not to specify complete subnet IPv6 address ranges, scanning these is extremely time consuming.

Excluded IP Address Range


Indicates the device range to be excluded from the previously defined range. The expected format is the same as for the included address range. This makes it possible to disable the scan for sensible devices even when using a short notation concerning the included device range (include: 192.168.1.0/24 and exclude: 192.168.1.255,mailserver,fileserver ).

Hardware Inventory

Yes

Defines if a hardware inventory is to be executed on the remote device.

Software Inventory

Yes

Defines if a software inventory is to be executed on the remote device.

Upload Policy

Immediate Upload

Indicates how and when to process the information upload. When set to Immediate Upload , the module does upload the inventories as soon as they are supplied by a scan. When set to Upload at Scan End , the inventories is uploaded when the scan is completed or aborted (except if the abort operation indicates not to upload). When set to No Upload , the module does not upload the inventories at all until specifically called for via the operational rule step.

Nmap Installation Path

../bin

Contains the relative installation path to the BCM software, relative to the agent installation directory, for example, ../bin if it is located in the bin directory of the agent.

Use Nmap for Port/OS Detection

Yes

Defines if BCM, if installed, is used to detect the ports and operating system of the remotely inventoried device.

Prevent NMAP from sending IGMP packets on the network

No

Check this box if some of your network devices have problems with IGMP traffic. In this case BCM is prohibited from sending IGMP packets on the network.

Sudo usage

Yes

Select the checkbox to connect using sudo (on Linux servers) to execute commands that require elevated privileges.
